IE11 using svg as background-image fails

Question

I'm facing a weird problem with Internet Explorer 11 running on Windows 10 machine. Using an SVG image as background thats appears totally black, Edge with the same code works fine.

Here a little fiddle reproducing my problem

Using this, Edge renders SVG rightly, IE renders only a black image...and i can't understand such a different behaviour! Furthermore, on a Windows 7 machine IE11 works fine!

Some ideas? Thanks in advance guys!

Answer 1

Make sure to set background size width and height

background-size: 80px 60px;

Answer 2

After digging into SVG file structure I found that problem concerns the SVG' styling properties.

Adobe Illustrator give me four options to declaring style sheet properties when saving graphics as an SVG file

1. Presentation Attributes
2. Style Attributes
3. Style Attributes (Entity Reference)
4. Style Elements

Accordingly to W3C specs regarding SVG1.1' Styling

No problem using the first three ways to styling properties, but embedding style sheets into SVG content inside a <style> element cause the problem!

Here my final fiddle test results

<div class="icon-user-default-css1"></div> <div class="icon-user-default-css2"></div> <div class="icon-user-default-css3"></div> <div class="icon-user-default-css4"></div>  

I hope will be of help to someone...
